Outcomes of Cataract Surgery in Eyes with Previous Herpes Zoster Ophthalmicus
To report outcomes of cataract surgery in eyes with previous Herpes zoster ophthalmicus (HZO).
Retrospective review of 24 eyes, with a history of previous HZO, which underwent phacoemulsification and intraocular lens implantation between 1995 and 2011 in the Cornea Service at the W.K. Kellogg Eye Center, University of Michigan.
Eyes with previous penetrating keratoplasty (PKP) were excluded. The information collected for analysis included the ophthalmologic history, visual acuity, pre- and post-operative adjunct treatments, and complications.
Results and Conclusion
Mean best corrected visual acuity improved from 20/115 (0.76±0.65 logMAR) preoperatively to 20/48 (0.38±0.48 logMAR) at one month after cataract surgery (P=0.031), but decreased to 20/70 (0.55±0.72 logMAR) at the last follow-up (P=0.605). Six patients had recurrent keratouveitis after cataract surgery, 3 of whom underwent PKP several years later for resulting corneal scarring. One patient had tractional retinal detachment from uveitis, which required vitrectomy and retinal repair.
Visual recovery after cataract surgery in HZO may be compromised by chronic extant factors, such as ocular surface disease and keratouveitis. In spite of long quiescent waiting periods before surgery and aggressive pre- and post-operative maintenance therapy, visual improvement may be blunted by the inherent pathological milieu associated with HZO. Nevertheless, with careful selection of patients, significant visual improvement may be frequently achieved even in this hostile ocular environment.
